RELATED APPLICATIONS

This application claims priority to, and the benefit of, U.S. Provisional Application No. 62/862,363, filed Jun. 17, 2019, which is incorporated by reference herein in its entirety for all purposes.

FIELD OF INVENTION

The present invention is directed to inhibitors of phosphatidylinositol-5-phosphate-4-kinase (PI5P4K) useful in the treatment of diseases or disorders associated with PI5P4K enzymes. In particular, the invention is concerned with compounds and compositions inhibiting PI5P4K, methods of treating diseases or disorders associated with PI5P4K, and methods of synthesis of these compounds.

BACKGROUND OF THE INVENTION

A minor but ubiquitous component of cells, phosphoinositol lipids are pivotal players in many intracellular signal transduction pathways. Phosphoinositol lipids are formed when phosphatidylinositol (PtdIns) is converted, by the catalytic action of lipid kinases, to polyphosphoinositides. As a prototypic example, the membrane associated phospholipid, phosphatidylinositol-4,5-bisphosphate (PtdIns(4,5)P2), is formed by two successive phosphorylations of PtdIns by the phosphotidylinositolphosphate kinases (PIP kinases).

PtdIns(4,5)P2 is a substrate for phospholipase C (PLC) and is converted into the second messengers inositol-1,4,5-trisphosphate and diacylglycerol (DAG). Phosphoinositides are involved in regulating a broad spectrum of activities from cytoskeletal assembly and motility to vesicle trafficking and exocytosis to transduction of intracellular signals including stimulating the release of intracellular calcium stores (Hinchliffe et al., Biochem. Soc. Trans., 1999, 27, 657-661).

PIP kinases comprise a unique and promiscuous family of enzymes that catalyze the production of polyphosphorylated inositol lipids from monophosphorylated phosphoinositides. Isolation and purification of several different PIP kinase enzymes able to catalyze phosphorylation of phosphatidylinositol 4-phosphate and produce PtdIns(4,5)P2 led to the further categorization of these enzymes, dubbed the phosphatidylinositol 4-phosphate 5-kinases (PIP5Ks), into two types having different activities. The PIP kinases have no homology to other lipid or protein kinases at the primary sequence level, and are distinguished from each other by their lack of immuno-crossreactivity and by the fact that type I PIP5Ks are stimulated in vitro by phosphatidic acid, whereas the type II PIP5Ks are not. Furthermore, the recent discovery that the type II PTP5Ks are able to phosphorylate multiple lipid substrates in vitro suggests that this family of kinases is potentially able to generate several distinct, often subcellularly compartmentalized, phosphoinositol products for regulation of a variety of physiologically important processes (Hinchliffe et al., Biochem. Soc. Trans., 1999, 27, 657-661).

One particular species of PI, phosphatidylinositol 5-phosphate (PI5P), has been implicated in the regulation of the tumor suppressor ING2 and the oncogene AKT. The phosphatidylinositol 5-phosphate 4-kinase (PI5P4K) family (α, β, γ isoforms) catalyzes the conversion of PI5P to PI4, 5 P2. These enzymes therefore represent one means by which cells can regulate endogenous PI5P levels. Mice deficient for PI5P4Kβ (PI5P4Kβ−/−) have been shown to exhibit enhanced insulin sensitivity and activation of AKT in skeletal muscle.

The pharmacological modulation of PIP5KII-beta activity and/or expression is therefore believed to be an appropriate point of therapeutic intervention in pathological conditions in which cell differentiation, proliferation, and/or motility are compromised, such as cancer or inflammation, and in metabolic disorders.

Currently, there are no known therapeutic agents which effectively inhibit the synthesis of PIP5KII-beta. Inhibition of PI5P4K with small molecule inhibitors, therefore, has the potential to be a treatment for cancers and other disorders. For this reason, there remains a considerable need for novel and potent small molecule inhibitors and agents capable of effectively inhibiting PIP5KII-beta function.

The details of the invention are set forth in the accompanying description below. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, illustrative methods and materials are now described. Other features, objects, and advantages of the invention will be apparent from the description and from the claims. In the specification and the appended claims, the singular forms also include the plural unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. All patents and publications cited in this specification are incorporated herein by reference in their entireties.

Definitions

The articles “a” and “an” are used in this disclosure to refer to one or more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element.

The term “and/or” is used in this disclosure to mean either “and” or “or” unless indicated otherwise.

The term “optionally substituted” is understood to mean that a given chemical moiety (e.g., an alkyl group) can (but is not required to) be bonded other substituents (e.g., heteroatoms). For instance, an alkyl group that is optionally substituted can be a fully saturated alkyl chain (i.e., a pure hydrocarbon). Alternatively, the same optionally substituted alkyl group can have substituents different from hydrogen. For instance, it can, at any point along the chain be bounded to a halogen atom, a hydroxyl group, or any other substituent described herein. Thus the term “optionally substituted” means that a given chemical moiety has the potential to contain other functional groups, but does not necessarily have any further functional groups. Suitable substituents used in the optional substitution of the described groups include, without limitation, halogen, oxo, —OH, —CN, —COOH, —CH₂CN, —O—(C₁-C₆) alkyl, (C₁-C₆) alkyl, (C₁-C₆) alkoxy, (C₁-C₆) haloalkyl, (C₁-C₆) haloalkoxy, —O—(C₂-C₆) alkenyl, —O—(C₂-C₆) alkynyl, (C₂-C₆) alkenyl, (C₂-C₆) alkynyl, —OH, —OP(O)(OH)₂, —OC(O)(C₁-C₆) alkyl, —C(O)(C₁-C₆) alkyl, —OC(O)O(C₁-C₆) alkyl, —NH₂, —NH((C₁-C₆) alkyl), —N((C₁-C₆) alkyl)₂, —NHC(O)(C₁-C₆) alkyl, —C(O)NH(C₁-C₆) alkyl, —S(O)₂(C₁-C₆) alkyl, —S(O)NH(C₁-C₆) alkyl, and S(O)N((C₁-C₆) alkyl)₂.

As used herein, the term “unsubstituted” means that the specified group bears no substituents.

Unless otherwise specifically defined, the term “aryl” refers to cyclic, aromatic hydrocarbon groups that have 1 to 3 aromatic rings, including monocyclic or bicyclic groups such as phenyl, biphenyl or naphthyl. Where containing two aromatic rings (bicyclic, etc.), the aromatic rings of the aryl group may be joined at a single point (e.g., biphenyl), or fused (e.g., naphthyl). The aryl group may be optionally substituted by one or more substituents, e.g., 1 to 5 substituents, at any point of attachment. Exemplary substituents include, but are not limited to, —H, -halogen, —O—(C₁-C₆) alkyl, (C₁-C₆) alkyl, —O—(C₂-C₆) alkenyl, —O—(C₂-C₆) alkynyl, (C₂-C₆) alkenyl, (C₂-C₆) alkynyl, —OH, —OP(O)(OH)₂, —OC(O)(C₁-C₆) alkyl, —C(O)(C₁-C₆) alkyl, —OC(O)O(C₁-C₆) alkyl, —NH₂, NH((C₁-C₆) alkyl), N((C₁-C₆) alkyl)₂, —S(O)₂—(C₁-C₆) alkyl, —S(O)NH(C₁-C₆) alkyl, and —S(O)N((C₁-C₆) alkyl)₂. The substituents can themselves be optionally substituted. Furthermore when containing two fused rings the aryl groups herein defined may have an unsaturated or partially saturated ring fused with a fully saturated ring. Exemplary ring systems of these aryl groups include, but are not limited to, phenyl, biphenyl, naphthyl, anthracenyl, phenalenyl, phenanthrenyl, indanyl, indenyl, tetrahydronaphthalenyl, tetrahydrobenzoannulenyl, and the like.

The present invention also contemplates isotopically-labelled compounds of Formula I (e.g., those labeled with ²H and ¹⁴C). Deuterated (i.e., ²H or D) and carbon-14 (i.e., ¹⁴C) isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances.

Analytical Methods, Materials, and Instrumentation

Unless otherwise noted, reagents and solvents were used as received from commercial suppliers. All solvents used were of analytical grade and commercially available anhydrous solvents were routinely used for reactions. Starting materials were available from commercial sources, or prepared according to literature procedures. Room temperature refers to +20-25° C. Solvent mixture compositions are given as volume percentages or volume ratios.

Microwave heating was performed in a Biotage Initiator microwave cavity producing continuous irradiation at 2.45 GHz. It is understood that microwaves may be used for the heating of reaction mixtures.

Straight phase chromatography was manually performed on Merck Silica gel 60 (0.040-0.063 mm), or automatically using an ISCO Combiflash® Companion™ system using SiliaSep™ normal-phase flash columns using the solvent system indicated.

NMR spectra were recorded on a 400 MHz (or higher field) NMR spectrometer fitted with a probe of suitable configuration. Spectra were recorded at ambient temperature unless otherwise stated. Chemical shifts are given in ppm down- and upfield from TMS (0.00 ppm). The following reference signals were used: the residual solvent signal of DMSO-d6 δ 2.5, CDCl3 δ 7.26 or Methanol-d4 δ 3.31. Resonance multiplicities are denoted s, d, t, q, m and br for singlet, doublet, triplet, quartet, multiplet and broad, respectively.

High pressure liquid chromatography (HPLC) was performed on a reverse phase column. A linear gradient was applied using for example mobile phase A (aqueous 0.1% NH₃ or aqueous 0.1% acetic acid or aqueous 0.1% formic acid) and B (acetonitrile or methanol). Mass spectrometer (MS) analyses were performed in positive ion mode using electrospray ionization (ES+).

Preparative chromatography was run on a Gilson-PREP GX271 or GX281 with Trilution 1c as software on a reverse phase column. A linear gradient was applied using for example mobile phase A (aqueous 0.1% NH₃ or aqueous 0.1% acetic acid or aqueous 0.1% formic acid) and B (acetonitrile or methanol).

Preparative chiral chromatography for separation of enantiomers was run on a Thar SFC using supercritical fluid chromatography on a chiral stationary phase. A linear gradient was applied using mobile phase A (carbon dioxide) and B (acetonitrile or methanol or ethanol or 2-propanol or any mixtures thereof). Additives (such as diethyl amine or isopropyl amine or ammonia or formic acid or TFA) may be used.

Biochemical Assays Example 3: ADP-Glo Biochemical Assay

Dilution series of the compounds were prepared in DMSO at 100 times the final assay concentration (n₁=n₀/3 in 10 points). The compounds were further diluted to three times the assay concentration in assay buffer (20 mM MOPS pH 7.2, 25 mM magnesium chloride, 0.005% Tween 20). 6 μL of the diluted compounds were added to a 384 well assay plate followed by 9 μL of a mix consisting of 4 nM PIP4K2A (full length protein, SignalChem) and 100 μM PI(5)P diC8 (Tebu-Bio). Enzyme and compounds were pre-incubated at room temperature for 15 minutes.

Then 3 μL of a solution containing 60 μM ATP (Promega) in assay buffer was added to the wells containing compound and enzyme and mixing was performed by pipetting several times. The reaction was incubated at room temperature for 1 h. Then 18 μL of ADP-Glo™ Reagent (Promega) was added to stop the kinase reaction and deplete the unconsumed ATP, mixing was performed by pipetting several times. The plate was incubated at room temperature for 40 minutes before addition of 36 μL of Kinase Detection Reagent (Promega) to convert ADP to ATP and introduce luciferase and luciferin to detect ATP. The reaction was incubated at room temperature for 40 minutes before the luminescence was measured in a in a Victor 3V 1420 multilabel counter (Perkin Elmer).

Percent inhibition of the compounds as compared to dimethyl sulfoxide treated control samples was calculated. Compound concentration versus percent inhibition were fitted to generate IC₅₀ values.
